Human IL-9 Receptor/CD129 PharmaGenie ELISA Kit (SBRS0791)

A core tool in cytokine signaling and immunology research, this Assay Genie ELISA Kit supports quantitative measurement of the human Interleukin-9 Receptor alpha chain (IL-9Rα, also known as CD129) in cell culture supernatant, plasma, or serum-derived samples.

IL-9R pairs with the common gamma chain to form a functional receptor for IL-9, a cytokine central to Th9 lymphocyte differentiation, allergic airway inflammation, IgE class switching, and immunity against helminth parasites.

Investigators working on asthma, atopic dermatitis, lymphoma biology, or cytokine-driven tumor microenvironments use this kit to track IL-9R expression and shedding in vitro and in vivo.

The microplate-based format accommodates 96 individual determinations and ships refrigerated for immediate use on arrival.

Reconstituted standards and detection antibody should be aliquoted and stored frozen to preserve binding activity through multiple freeze-thaw cycles.

Results may be cross-validated with downstream flow cytometry, immunohistochemistry, and Western blot workflows that probe CD129 protein expression at the cellular and tissue level.
